They released their first a clutch last night. Unfortunately our filtration system ate them. We only collected 5 which we dumped in with our few week old H elegans larvae. They will probably be eaten. We will change our filter screens the larvae were much smaller than the H. elegans larvae

May 23 We have been checking the egg clutch 3x daily for signs of hatching for the past 2 weeks.

The eggs were getting larger each day. They were there the night of the 21st and gone the morning of the 22nd There were no larvae and the eggs were all gone. There were no signs of any larvae in the filter sponge on the tank. I am guessing she dropped the clutch and the bristle worms ate them all.

It doesn't make too much sense. The eggs must have been fertile because they were getting larger.

On another note: Our pair of shrimp is not the brightest. I am not sure if I can blame them but between them and the bristle worms the starfish is dead long before the shrimp finish eating it. The starfish starts to rot and has to be removed

Our female died so we took the female from our H. elegans pair and paired her with our male H. picta. We have a few survivors of their first hatch in a Kreisel now. We also have obtained a second smaller pair of H. picta. They have not spawned yet. Both pairs of picta and the mixed pair killed the starfish long before they were done eating it and we had to discard the rotting remains. All the pairs of elegans we had over the years had no problem keeping the starfish alive until the end. To keep from wasting starfish we feed the bits and pieces.

We obtained a new smaller Hawaiian pair a few months ago They had a larva release today 10/3/2017 Rather than chase them with a baster I strained the tank water through a 105 micron net and returned the water to the parents tank and put the larvae in a Kreisel. I am guessing there were way over 1000. I dumped in a quart of T-iso and 4 quarts of parvocalanus

On November 10th our Hawaiian pair released a clutch We moved 150 of them to a Kreisel for growout

On December 18th we had 24 so far settle out at 38 days. They are much smaller than the Indonesian harlequins we raised before but the also settled out much earlier They were fed enough Parvo 2x daily to keep the parvo density at 3-4 per ml We added 500ml of iso daily to the Kreisel. At 30 days they were transferred to another Kreisel to avoid hydroid infestation. The ones that have settled have been transferred to a 55 gallon grow out tank

This is what has settled so far and the dates 24 on Dec 18 7 on Dec 20 27 on Dec 24 12 on Dec 27 5 on Dec 28 6 on January 1st There are still some twirling arround that haven't settled yet The stretched out settlement period might be a food issue We are having an iso issue so we don't have any parvo to feed and have switched to apocyclops

We had a total of 81 Hawaiian Harlequin shrimp settle The parents released over a thousand larvae Due to the large amount of copepods required to raise them we only collected about 150 to raise to settlement Settlement took place over a 19 day period., At the beginning of settlement we ran out of parvo and iso and had to feed apocyclops grown on rotigrow. That may have stretched out the time to settle

As opposed to the Harlequin shrimp from Indonesia The Hawaiians: were much smaller and greener as opposed to brown at release settled in less time and were smaller at settlement are a different color (more yellow)

Adult Hawaiian Harlequin shrimp: tend to grow larger than Indonesian shrimp are yellower Are not as adept at keeping a starfish alive until it is all consumed

We have mixed pairs and they have produced larvae. We have not got them to settlement yet

The two "species" are reproductively isolated from each other. are most likely capable of producing fertile mixed offspring but that remains to be seen Have different characteristics (color, larval, juvenile and adult size) Appear to have different settlement periods
